This Wave Tug has been upgraded from her sister (ALN 057) and she is a powerful and robust in field support boat that serves as a daughter craft to an AHTS operating in Angola. The hull-form is optimised to give a high bollard pull for heavy line and hose handling duties and the skeg configuration allows her to sit on the deck of a mother ship without a cradle. She is fitted with a capstan and tow post aft for line handling and an access platform at the bow for personnel transfer.
